I know that unauthorized immigrants are for the most part good, decent people. Deploring illegal immigration is not a condemnation of the immigrants themselves, anymore than deploring traffic is a condemnation of drivers. The rhetoric about hard workers trying to support their families is true, and in a perfect world we could invite everyone in without any tradeoffs. But the United States cannot take in millions upon millions of impoverished workers and hope to provide its own low-income citizens with lives of dignity or economic security.
